Keep in mind that you are looking for quality clicks over quantity. I think it is awesome to get that many clicks for that budget...but I think what you should be focused on is how many of those clicks are converting for you. That should be your measure of success in my opinion...unless of course your goal is to get as much visibility as possible. Either way...hope this helps. -Andy
As always it depends on the niche, but I would say that is a good level of earnings for that many clicks if the site is just a general entertainment type site. If, of course, it was a more serious topic such as Health or Medical then you should be earning far more.
